To all whom it may concern:

Be it known that; l, l nnonmon RAVEN, a, British subject, residing atKorrumbui'm, in tho of Victoria, Golnmonweztltli of Australia, haveinvented certain new and us fill Iimprovements in Milking- MiLCllll'lf"ind Cmlmgciions, of which the. following is a specifii The ob of myinvention is to simplify and improve mi machines and tent cups usedtherewith, By rcfcrer to the accompanying sheet of drawings theinvcnrion. will be clearly understood.

.Throughou'tihc drawings the figures represent like Figure-l is avertical pulsstor valve upon its bed or body, constituting the firstpart of my invention, anodjusting link and :1, portion of the eccentricrod connection ore also shown. Fig. 2 is a; vertical side elovotion'oiFig. l. but without the adjusting link and eccentric rod connection.Fig. 3 is a vertical sectional view of Fig. 2 showing the inte- FlOIfOTm oi tho'soid pulsstor valve and the valve bed or body for some. Fig.4 is an elevation of said pulsaior volveflzice. Fig. 5 is a. sidesectional view of my fie-lit cup und its combination of partsconstituting the second part of my present invention. Fig. 6 is on endolevation partly in section of Fig. 5 showing the sec? tional view ofone of the two horizontal grip ribs contoined within each of said testcups. Fig 7 is an enlargcd plan or View oi the bztlllc disk or pin-to(removed) sud three equidistant bayonet cotchessrouiid its rim. Fig. 8is also-on enlarged partial view of one of the three grooves in whichthe said bayonet catches slide when introduced into'sa-icl test cup.Fig. ll is a generiil 'view of the position and arrangement of the essential parts of my invention and connections in practice.

In this View two sets of Lent cups are shown one being enlarged forclesrncss of illustration. 7

In the drawings (1) represents the pulsotor valve rectongulorly shapedand provided with the vacuumv mid milli suction chamber (2), twoatmospheric inlets (3) min (4) and the spy or milk inspection glass,(5). Througlrs'oid iulsstor valve (1) ore made the said airinlets (3)ond (4)310 inner ends of which are extended into transverse grooves (6)made nearly across the face (7) of the p'ulsotor valve (1) its shown inFigs. 3 and 4.

Said plIlSZL'CU! valve (1) carries the rib arm (8) having frontelevation oi thosliding' 7 mid octagonslly slur-pod cap (17) which isscrew threaded internally to it upon the sci-ow threaded spigot (18)projected from said pulso-tor vnlvc (l). The end of sand spigot forms alaced slmuldcr (19) between which and the lncod inuor circular shoulder(20) of the cap (l7) placed the im'lio-rubborwasher (21) and the glossspy (5').

so that said bed may be securely fixed by screws to the vertical post(26) as shownin Fig. 9. valve bod (16) has also three ports (22), (23)and (24), the ports (22) and (23) and tubing (:27) and (28) areconnected with the two sets of toot cups (29) and (30) respectively, and,the other port (524) communicates with the tubing (31) and scaled milkbucket (32),wl1ile the vacuum tubing (33) is connected with said bucketand a common doilblo' acting vacuum pump not shown in the drawings itspurpose and operation are both well understood.

The teat cup as shown at Figs. 5 and 6 consists of the inr'lisi rubbercasing or shell (34) and is formed solid Witlrtlio two test grip ribs(35) projected one opposite to the other near the upper internal sideportions of said toot cup while the upper part of said casing is formedinto a circular ring (36) which serves as the month piece whereby thevtoot cup may fit well up against the cows udder. The bulged out parts(37) of the tent cup render it somewhat poor-shaped as at Fig. 5 so asto provide end air compression spaces for the quick intermittentinduction oi atmospheric itir after the vacuum in such cu i lias beendestroyed.

(38) is. the boi'lie disk or pliite which is made about one fourth of aninch less in diameter thoirtlie internal diameter of the lower portionoi said test cup and is provided with three bayonet catches similar .to(39) shown in Figs. 5 and 7. These bayonet catches fit tightly in theinverted L shaped grooves (40) (Fig. 8)

said invention is as iollows:ll1o two milking tubes (27) and (28)"arefirst connected with the ports (22) and (23) and the vacuum tubing (31)with the other orcentral port (24) of the body (16) and the milk bucket(32), while the tubing (33) is connected with said bucket (32) and thevacuum. pump. The two sets of teat cups are 1111611 placed upon the cowsteats and tli machine set going. This is effected by the employmeni; ofan. oil or other suitable en gine to work a driving shaft which carriesan eccentric to verticollyrecibro" The vertical stroke of Sftldpulsator' The bclorc mentioned pulszitor valve bed (1.6) li11s foureiu's'or lugs (25) m.- GilCll of its corners sator valve (1) which movesacross the ports (22), (23) bsflle disk or plate (38) sprays or deflectsthe milk on and (24.). When the valve is on its down stroke the to theannular wall of the teat cups, thereby preventing vacuum from the pumpacts upon the first set (29) of i the tent cups and during this downstroke period the milk is sucked or drawn from the tents up to thebottom port (23) thence into the chamber (2) of the pulsator valve (1)where it can be seen by looking through the spy glass (5) therebyallowing the attendantto ascertain whether or not the cow is stripped.During the some down stroke period the atmospheric air is admittedthrough the top air inlet (3) of the pulsstor valve (1) top port (22) ofthe body (16) tubing (28) and cups thereby destroying the vacuum thereinand at the some time releasing momentarily the pulsated grip of thesecond set (30)'of teat cups. The upwerd stroke of the said pulsstorvalve (1) also delivers by suction the milk from said chamber (2) intothe central port (24), thence into the vacuum tube (31) through which itruns to the milk bucket (32) simultaneously by allowing the atmosphericair to enter the lower port (23) and milk tube (27) for the purpose ofdestroying the vacuum in the first 'set (29)bf test cups, in which case,and at this juncture the vacuum acts upon the second set (30) of testcups drawing the milk therefrom into the top port (22) and chember (2)of pulsator valve, thereby delivering it to said central port (24)tubing (31) and into the milk bucket. In

this manner on alternate pulsztted grip suction and release take placewithin and uponthe first and second sets of teat cups and should anyback flow of milk occur in the teat cups during the process of milkingthe said back-flow from irritating the tents of the cow.
